I had a friend over for movies last night, we couldn't figure it out and wound up using the computer. Now the sound on my Direct TV Is working but the screen is blue and says no signal.

HI there
I thought I was the only one who had movies inmy home I have friend come over for movies every wednesday.
Now there is a challange:
Try to ajust the brightness and contrast in the PICTURE menu
What the "no signal" concerns check if the signal cable is connected between the tv and products properly, as well as checking the selected input source by pressing input.
